Foods that promote healthy nail growth include those rich in biotin (such as eggs, nuts, and seeds), vitamin E (such as spinach, almonds, and avocado), and omega-3 fatty acids (such as salmon, chia seeds, and walnuts). Additionally, foods high in zinc (like chickpeas, lentils, and pumpkin seeds) and iron (such as red meat, lentils, and dark leafy greens) can also support nail health. Don't forget to drink plenty of water and stay hydrated to keep your nails strong and healthy.
